ADDING AND LISTING MACHINE.

Application filed December a, 1909. Serial No. 531,2.

To all whom it may concern: H

Be it known that I, Jessa G. Vmcnm,

a citizen of the United States; residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Adding and Listing.

Machines, of which the following is a specification. v

The primary object of the invention is to equip an adding and listing machine with means whereby lists of items may be printed upon separate strips or sheets of paper independently fed or advanced step y step from ,a common actuating member whose operative relationship with one or another paper feed means is automatically determined by the lateral shift of the paper carriage.

The invention further provides for automatically controlling a duplex accumulatin mechanism so that items or amounts liste on one strip or piece of in one accumulator whi e items or amounts listed upon the other strip or piece of paper will be added in another accumulator, the operativeness of one or the other accumulator being determined by the lateral shift of the carriage.

In the drawings which accompany and form" part of this specification Figure 1 represents in left side elevation an adding and listing machine equipped in accom lish results such as above mentioned; i 2 is a rear elevation of such machine; l ig. 3 is a top plan view of the pa r carriage with portions of the sectional rol er platen broken away; Fig. 4 is a sec line 4-4 5 and 6 are similar fragmentary top an views of a portion of the key-board; i 7 shows a portion of the machine in lo t side elevation with arts under a different adjustment than lllustrated in Fig. 1; Fig.8 is a partial rear elevation illustrating a different adjustment than appears in Fig. 2; Fig. 9 is a perspective detail of a carriage stop-piece.

The invention is here shown as adapted to the well-known Burroughs type of adding and listing machine fand particularly to that development thereof which includes the duplex accumulating idea, in which connection reference may be had to Patent No. 919,656, issued April 27, 1909, on the joint invention of-myself and Nelson White. It

tion takenwsubstantially on t of Fig. 2; Fi

aper will be added does.

there is pivotally mounted upon the upper part of this carriage a rocking frame or cradle 17 by the forward'movement of which paper to be printed upon is brought into proper position for receivingimprints.

In the resent instance this rocking frame or credit does not carry the usual cont-inuous roller platen but there is journaled in it two alined roller platens A and B (Figs. 2 and 3) each secured to its own shaft or spindle and arranged to be turned ste by step independently of the other. shafts l and BQjournal in the end-pieces of the rocking frame or cradle in the same way-that the customary sin le laten shaft At their inner en 5 t es'e shafts journal in a bushin a (Fig. 3) secured in a plate l7 carried iy the cross rod 17 of the cradle and the cradle rock shaft 17". The inner ends of the two roller platens are preferably closed by heads a and b secured to them and to the shaftsA' and B respectively and center-bored to accommodate the bushinga. Each of the platen shafts is turned by a ratchet-and-pawl mechanism and as one such set of devices is the same as the other a description of one will suffice. A ratchet wheel A is secured to the shaft A and a pair of arms C loose on said shaft carry a pawl D pivoted between them and drawn by a spring 0 toward the ratchet wheel and normally prevented from engaging the same by the contact of a cam finger (1 with the projecting end of the journalshaft 17 of the rocking frame or cradle,-all as shown in Fig. 1. A link E connects the pair of arms C with a plate F, the latter slotted and socketed for the engagement of-a stud 6 carried by the link. Referring next to Fig. 4 the plates F are secured to separate rock shafts A and B and these rock shafts carry bails composed of cross rods A and B and arms f connecting the same with the rock shafts.

It will be seen that the above-described construction provides for step-by-step advance of either roller laten quite independently of the other. fIowever. the same actuating member serves for bath platens The p aten Specification of Letters Patent.- Patented Aug. 23, 19 10- i 1s printe the jaws and the other in between the jaws when the carriage is shifted. The plate 18 is reciprocated in the usual way by a lever 18' coupled at the rear end to the plate, and a cam 18 secured to the rock shaft 100 and having a slot embracing a roller 18 on the forward end of the lever 18",all as shown in Fig. '1. w

It will be understood of course that separate strips or sheets of paper will pass around the two roller platens. In the present instance holders A and B (Figs. 1 and 2) are shown designed to carry two separate rolls of paper and having well-known or any suitable equipment for keeping the strip or web of aper in the proper line the holders being aterally adjustable on their supporting cross-rods' These separate webs of paper will be entered between their respective platens and suitable pressure rollers A", B and one web or the other will be advanced according to the position of the tan ria e, said pressure rollers being independent y rotatable. It will be seen that the arrangement described provides for printing upon one web of paper and advancing the same without the other web of paper-being afiected at all. Then the carriage can be shifted and the web of paper previously rinted u on is not affected when the other u on and advanced. Two separate lists 0 items can thus be run off on separate pieces of paper in the same machine and by' the operation of the same actuating member and without feed'movement of the. piece or web of paper not in use.

It is of course desirable that each roller platen have the usual facilities in the matter of turning by hand in one direction or the other and therefore each of the shafts A and B carries at the outer end a knob or twirler A, 13.- Then there is provided for each platen the usual dolly' roll 1 springheld in engagement with the associated ratchet wheel, as illustrated in Figs. 1 and 2, for the purpose ofpreserving the proper spacing when the platen is rotated.

To fix the carriage in the proper lateral osition or positions there is secured to the ack of the machine a notched plate H and on a rock shaft G in'the lower part of the carria ethere are adjustably secured fingers H a apted to erfgage the notched late, bein constrained to do. so by spring appliet to lever h loose on shaft B and cranked to saidlrock shaft (Fig.2). The same pieces of which said fingers constitute parts are utilized for the purpose of controlling the du lex accumulating mechanism flanges of the two fingers herein shown are adapted to act against vertical shoulders of a plate I on the rear of the, machine (see Fig. 2). This plate is slotted longitudinally to embrace guiding studs 5 on the casing or framework of the machine and is adapted to he slid one way or theother by action of the flanges 72. against the said vertical shoulders. The latter are designated respectively z" and i and are at opposite ends of a raised portion of the plate; This raised portion is not of great extent and may of course vary in extent but as here shown it provides for the shifting of the carriage a comparatively limited amount tochan e from one web of paper to the other. 0 course this raised portion measures; the minimum extent of such shifting of the carriage and the. fingers H can'of course be spaced apart varying distances to provide for a greater extent of shift of the carriage. Under the adjustment illustrated in Fig. 3 it will be seen that the carriage moves a. considerable distance before the shoulder i is encountered by the flange of the stop finger. This arrangement provides for varying conditions as to width of paper without requiring any adjustment other than thesetting of the stop fingers.

The slidingplate I has a depending portion formed with an-oblique slot 2' which receives a roller j on an arm J ,.the lattersecured to a rock shaft j in a bearing on the back of the machine and carrying at the inner end another arm J, (Figs. 1 and 7; see also dotted lines, Fig. 8). This arm J is pivoted to a link 9' and the latter is pivoted to an arm 7' secured to a rock shaft 501 carrying another arm 7'. Loose upon the shaft 501 is an upstanding arm K to which is pivoted a link]: which at its forward end is pivoted to the lower end of a lever 10 corres onding with the lever "so designated in said Patent No. 919,656. The aforesaid arm K has'a roller stud k which co-acts with a V-shaped cam L on a curved arm L pivoted to the arin y" and connected by a sprin j? with an ear on the hub of the latter, as s IOWXI in Figs. .1 and 7 With the carriage in the right-hand position, as illustrated in Fig. 2, the arm J is elevated by reason of the roller 7' being in the upper end of the oblique cam slot 2' and in consequence the inner arm J is down as in Fig. 1 and the'arm 7" up' with the V-shaped cam L'to the rear of the roller stud k, as shown in Fi 1, the arm K being thus held forward, Vh the left the plate I is likewise shifted and the arm J is rocked to the position shown in Fig. 8 and the arm J correspondingly eleboard plate and connected to a slide vated so that the V-sha ed cam L is carried to the front. side of t e roller k and the spring causes said cam to shift the arm K rearward as illustrated in Fig. 7. This shifting of the arm K throws the lever 10 back and forth the same as it is moved by hand in the construction described in said patent and with like result in alternately rendering active the department of the duplex accumulating mechanism.

The accumulatin mechanism is practically the same as lustrated in said patent and a full description of it need not be given since such will found in said patent to which reference has been made. Suflice itto state that the pinions of the upper accumulator are desi ated -618 and'those of the lower accumu ator 618 and that with the carriage in the right-hand position the upper accumulator is active, whereas with the carriage in the lefthand position thelower accumulator is the active one.

It will be obvious that the arrangement described insures that items listed upon the web of paper at the left of the carriage will be accumulated in the upper accumulator and that items listed upon the'other web of paper will be accumulated in the lower accumulator.

Instead of having the lever 10 project above the keyboard as in said patent it is here shown as cut of! below the upper lieyate 10' inscribed with the letters U and L indicating u r and lower accumulators, such letters mg adapted to be alternately displayed through an opening in the keyboard, as illustrated in gs. 5 and 6. This or any other distin ishmg arrangement can .be employed to enote to the user at a glance which one of the accumulators is ready to receive items. Instead of the letters or in addition thereto contrasting colors may be used.

:While the above-described construction is well adapted to fulfil the object primarily stated, it is to be understood that such construction can be modified considerably within lhe scope of the invention.
